WILLIAM F. BLAKE, 0F TOLEDO, OHIO, ASSIGNOR 0F FIFTY-ONE PER CENT. T0 HENRY W. IDUVENDACK, OF TOLEDO, OHIO.

oANprENER.

Application filed June 25, 1917.

To all whom it may concern:

Be it known that I, WILLIAM F. BLAKE, a citizen of the United States, residin at Toledo, in the county of Lucas and btate of Ohio, have invented a new and useful (Jan-Opener, of which the following is a specification.

My invention relates to improvements in can openers; and the objects of my improvement are, first, to provide a can opener with a blade having two sharp cutting edges; second, one in which the blade may be readily removed and sharpened; third, to provide a can opener with a safety blade guide so that ones fingers are not injured by blade sliding off of can top; and, fourth, to provide a can opener that has a cutting leverage and that will always out smoothly and close to the edge of the can.

I attain these objects by the mechanism illustrated in the accompanying drawing, in which Figure 1 is a View of the can opener as a whole; Fig. 2, a view of the front edge of the can opener; Fig. 3, a sectional view on the line 33 of Fig. 1; and Fig. 4, a detail view of the fulcrum on the line H of Fi 1.

imilar figures refer to similar parts throughout the several views.

The can opener consists of the handle 1 made preferably of metal, and the blade 2 with the two cutting edges 8. The blade 2 is securely fastened to handle 1 by the screw 3 and thus is readily removed so that edges 8 can be sharpened whenever necessary. The safety blade guide 7 extends beyond the blade on every side so that if the can opener slips from the can while cutting the sharp blade can not strike your hand, nor when lying in a drawer or on the table will you run your fingers against the blade. The blade guide 7 is a part of handle 1 but is not so deep thus forming a recess 9' between the blade 2 and the guide 7 and just below fulcrum 4., this recess engages the top of a can when opening same.

The fulcrum 4 is made of hardened steel and is fastened to the handle 1 by the screw 5 so that it is just back of the edge 8 of blade 2. Fulcrum 4 always rests on the edge of the can when using the opener and thus provides a permanent leverage as the blade cuts for its entire length and prevents the opener from slipping about, the down- Specification of Letters Patent.

Serial No. 176,819.

ward'projection 6 of the blade guide 7 being always on the outside of the can also aids in holding the can opener close to the edge of the can.

The operation of my can opener is easily understood, the blade 2 is placed upon the top of a tin can in a nearly vertical position and forced down through the top with the hand or some instrument until the blade pierces the metal. hen the blade 2 is inserted in the metal top the projection 6 of the blade guide 7 is necessarily on the outside of the can, now press down on handle 1 and as the opener rests on the fulcrum 4. giving a permanent leverage, a very small pressure is required to cut through the metal the full length of edge 8, then the process is repeated until the required opening is made, which will be found to have a smooth edge with no jagged pieces of tin to out your hands when removing contents of can.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a can opener, the combination of a handle with a blade guide on one side of the lower portion of said handle, and at right angles from and adjacent thereto a round adjustable fulcrum with a sharp cut- ..ting edge to engage the edge of a can.

2. In a can opener, a handle having transversely spaced guide and blade members at one end, and an adjustable fulcrum member adjacent to the inner end of the crotch formed by the guide and blade members.

3. In a can opener, a handle having transversely spaced guide and blade members at one end, and a rotatably adjustable disklike fulcrum member carried by the opener adjacent to the inner end of the crotch formed by the guide and blade members.

4. In a can opener, a handle having transversely spaced guide and blade members at one end, and a disk-like fulcrum .member carried by the opener adjacent to the inner end of the crotch formed by the guide and blade members, the fulcrum member being rotatably adjustable in a plane which is transverse to the plane of the crotch openmg.
